[Experimental animal studies on the possibilities of bone reconstruction using preserved allogenic material].

Preserved allogeneic bone is possibly to repair the permanent shortness in autogeneic bone tissue in clinical practice. Complications as to the incorporation were observed after using lyophilised allogeneic implants. These were attributes to immunologic defense reaction. Demineralised bone caused a more intensive bone regeneration histologically than lyophilised bone. The clinical test of a superficial demineralised lyophilised preserved bone with osteoinductive potency and structural stability is recommended.
